Procurement Notes
Verify RoHS compliance status prior to procurement. Confirm that the specific ordering suffix matches the required contact plating and housing color specifications. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any specific handling requirements related to the solder tail termination process during assembly.
Selection Notes
Select this component when a dual-row card edge interface with a 0.156-inch pitch is required. Ensure the target PCB design accommodates the 0.062-inch thickness specification. Verify that the operating environment falls within the -65°C to 125°C temperature range. Consider the through-hole mounting requirement for mechanical stability.
Part Context
This part belongs to the EDAC 306 Series, which specializes in card edge connectors with a 0.156-inch contact spacing. The series offers various position counts and termination options. The 306-022-521-102 specifically denotes a 22-position variant with dual rows and gold-plated contacts, suitable for standard industrial and commercial electronic applications.
Replacement Considerations
Cross-reference with other EDAC 306 series parts for alternative position counts. Verify compatibility with existing PCB footprints before substituting. Ensure mating card edge dimensions align with the 0.156-inch pitch specification.
